Restores the Custom Field meta box for the Gutenberg Block Editor.
Update: This plugin currently is not needed, as WordPress version 5.0+ displays Custom Fields natively. Just click the settings button (three dots) and go to Options, where you will find the option to display the Custom Fields meta box. So this plugin still works great, but it is recommended to use native WP custom fields instead.

MB FacetWP Integration is a free plugin that integrates <a href="https://metabox.io" rel="nofollow ugc">Meta Box</a> and <a href="https://facetwp.com" rel="nofollow ugc">FacetWP</a>, which makes custom fields of Meta Box searchable and filterable in the frontend.
<blockquote>
Meta Box Lite 
 We recommend using <a href="https://metabox.io/lite/" rel="nofollow ugc">Meta Box Lite</a>, a feature-rich free UI version of Meta Box that provides UI and all free features for managing custom fields and dynamic content on WordPress, including post types, taxonomies, custom fields, and relationships.
</blockquote>
For an e-commerce or a listing website, the product or listing requires custom data such as price, location, color, etc. And users need to search or filter the products / listings in the frontend based on these criteria.
<ul>
<li>With the help of Meta Box, you can create any kind of data (custom fields) for your product / listing or any custom post type.</li>
<li>And FacetWP will make products / listings searchable, filterable by those data.</li>
</ul>
This plugin doesn’t require any configuration. Just install it and you will see Meta Box custom fields appear in the list of options in FacetWP settings.
